Neutrino oscillations in gravitational fields and astrophysical applications

TL;DR

This paper investigates how neutrino oscillations are affected by gravitational fields, including black holes and gravitational waves, with implications for astrophysics.

Contribution

It introduces a comprehensive analysis of neutrino behavior in complex gravitational environments, including spin precession and stochastic gravitational wave effects.

Findings

Neutrino spin precession occurs during scattering off black holes.

Flavor evolution is influenced by stochastic gravitational waves.

Astrophysical phenomena can be better understood through these neutrino-gravity interactions.

Abstract

The neutrino propagation and oscillations in various gravitational fields are studied. First, we consider the neutrino scattering off a black hole accounting for the neutrino spin precession. Then, we study the evolution of flavor neutrinos in stochastic gravitational waves. The astrophysical applications of the obtained results are considered.
